buffered

(USPTO)The Patent Description & Claims data below is from USPTO Patent Application 20070240504. Brief Patent Description - - CROSS REFERENCE TO RELATED APPLICATION[0001] This application is a continuation-in-part of U. S application Ser. No. 08/500,004 filed Jul. 10. 1995 which is a continuation-in-part of U. S application Ser. No. 08/439,502 filed May 11. 1995 both entitled "Local Buffer Circuit". BACKGROUND OF THE INVENTION[0002] 1. Field of the Invention[0003] The present invention relates to magnetostrictive displacement or distance measuring transducers and more particularly to magnetostrictive transducers having modular construction including for displacement or distance measuring and adapted for easy configuration of assembly of field equipment after manufacture or assembly from stocked modules. This construction also facilitates modular construction of an explosion-proof field device.[0004] 2. Description of the Art[0005] Magnetostrictive transducers having elongated waveguides that carry torsional strain waves induced in the waveguide when current pulses are applied along the waveguide through a magnetic field are well known in the art. A typical linear distance measuring device using a movable magnet that interacts with the waveguide when current pulses are provided along the waveguide is shown in U. S. Pat. No. 3,898,555.[0006] Devices of the prior art of the sort shown in U. S. Pat. No. 3,898,555 also have the sensor element embedded into the protective housing which also houses the electronics to at least generate the pulse and provide certain mounting means associated with the device for the customer.[0007] U. S. Pat. No. 5,313,160 teaches a modular design in which the sensor and electronic assembly can be removed from the application package. In the application package is the outer housing which is used by the customer for mounting an attachment of the sensor and electronics assembly with the end device whose position is to be measured. Sensor designs of the past have required delicate handling until the fabrication of the total unit including the outer housing and electronics has been completed. Prior art also utilizes difficult to produce and expensive methods to suspend the waveguide and to prevent the reflection of the desired sonic strain wave. Prior high performance waveguide suspension systems utilize thin elastomer spacer discs which are individually positioned along the entire length of the waveguide. Installation of the discs is a time consuming usually manual operation. The best performing damping devices in use utilize molded rubber elements with a central hole. These are difficult to mold and time consuming to apply.[0008] The prior art has deficiencies in that the electronics are included within the waveguide suspension device and an expensive means for waveguide suspension is utilized. The prior art also has deficiencies by not having modular construction and pre-assembled sensor elements. Further if different sizes are needed the unit must be removed. But in the prior art the sensor and the electronic package were not removable and interchangeable because of the application electronics being attached.[0009] It is an object of the present invention to provide for an easy configuration or assembly of field equipment after manufacture or assembly from stocked modules including modular construction of an explosion proof sensor.[0010] It is a further object of the present invention to remotely locate the sensor from the electronics. SUMMARY OF TE INVENTION[0011] The present invention relates to a modularly constructed magnetostrictive transducer of the sort set out in U. S application Ser. No. 08/500,004 filed Jul. 10. 1995 having a modular constructed magnetostrictive transducer permitting a pre-assembled sensor element. A sensor cartridge which may be used as an explosion proof probe and which is environmentally protected and mechanically strong for direct use in process control applications is disclosed. The outer housing can be made from any weldable metal and a sheet of teflon or other plastic can be added if needed for chemical resistance. The pre-assembled sensor elements allow easy configuration or assembly of field equipment after manufacture or assembly of the sensor element. It also permits potting for environmental seal and explosion proof construction. The transducer would be then a rugged component and may be equipped with threading to thread to another explosion proof housing which contains the mating electronics. For explosion proof configurations the explosion proof material is anchored within the housing to be held in place when exposed to higher pressures. DESCRIPTION OF THE DRAWINGS[0012] For a further understanding of the nature and objects of the present invention reference should be had to the following figures in which like parts are given like reference numerals and wherein:[0013] FIG. 1 depicts a side elevated view of the complete sensing element assembly;[0014] FIG. 2a is a cross-sectional view of the sensing element assembly of the preferred embodiment of the present invention of FIG. 1 taken along section lines 2-2 of FIG. 1 showing a portion of the waveguide and surrounding sleeves showing the damping element at the end of the waveguide;[0015] FIG. 2b is the same cross-sectional view of FIG. 2a but showing a first alternative of using a tuning wire between the damping element and the waveguide;[0016] FIG. 2c is the same cross-sectional view as FIG. 2a but shows a second alternative of external tube crimped over the damping element;[0017] FIG. 2d is the same cross-sectional view of FIG. 2a but shows a third alternative of the return wire in a different position and with an external tube crimped over the damping element;[0018] FIG. 3 depicts an elevated end view of the housing which shows the connector;[0019] FIG. 4 is a cross-sectional view of the sensing element assembly of the preferred embodiment of the present invention of FIG. 1 taken along section lines 4-4 of FIG. 1 showing the cross-section of the housing and a portion of the waveguide and surrounding sleeves but not showing the damping mechanism;[0020] FIG. 5 is a plan view of the bracket of the preferred embodiment of the present invention;Continue reading...

Sometimes it feels like I'm perceived this way. It's not generally something I consciously do--shield myself from the world for in many ways. I think I am very open and alter myself pretty vulnerable. But there are other days when others claim I am all walled in. I have one *friend* (he's deemed me his best friend in fact how much of a friend he is for me seems to be pretty inconsequential in terms of his actions) in particular right now who's regularly frustrated I don't share more. But it's hard for me to overlap more because he's a member of my congregation and there are a whole host of things happening right now that are confidential so I can't talk about them. This man also has a habit of pushing and digging with all his might into areas where he has been given an advance of information and quite frankly there are other parts of my life where I don't want anyone pushing and digging for more information. In many ways I think our willingness to be vulnerable is a product of our environment--we learn to wear extra padding or not and we learn to read the signs of when it is safe to take that padding off. I guess I'm more like Mr. Padding than I'd like to admit at least these days. It doesn't feel safe to overlap. It doesn't feel safe to bear the truth of my heart. I be a buffer these days because I'm not sure I can act another blow hat tip for the draw: I'm a United Methodist pastor(a) working cross-culturally as if I were Latina and Americana at the same time--a mestizo identity of my own. I'm a thinker a do-er and a helperyo soy una pastora en la iglesia metodista unida. Me veo con un mestizaje de lo americano y lo latino. Me gusta pensar ayudar y hacer.

NIFORUMS POSTHello. My general goal is that I undergo a "dominate console" running on a LVRTOS PXI and I am trying to undergo a VI on the Host PC send and recieve these console commands. So far I have tried to send a string of characters to a PXI using a Shared communicate Variable. The problem is the VIs I have created so far result in the string being output repeatedly at the speed of the PXI's loop. This makes comprehend but I was attempting to have a single string "consumed" by a read even and I attempted to use the Queue objects to do this. However they appear to not be "transportable" over the communicate. I assumed that enabling buffering on the Shared Network Variable would help this problem (it is a "buffer" so once a read occurs hopefully an item is removed from the buffer). However the behavior does not change as buffering is enabled or disabled for this string-based Network Variable. At this point I realize TCP is going to be an option but using the Shared communicate Variable for this is convenientfor other several other reasons. Does anyone have any suggestions? I beleive you can right-click on the shared vaiable node and get it to return a timestamp. Any time the measure stamp changes there should be a new arrange. Hi Ben,I implemented your suggestion a week ago and it was working quite come up until our transmit rates started to increase. Timestamps only undergo a resolution of 1ms. If I start transmitting large blocks of commands (parsing a textfile) quickly two strings could have different content but be sent in the same millisecond thus failing the conditional evaluate and dropping a command. I noticed on my "local" machine a queue coordinate works perfectly but I can't "overlap" a queue via a network shared variable. Perhaps you could create your own cluster datatype for the shared variable where you have a numeric value and the desired data string. Everytime you put in a new string increment by 1 the be you put in the numeric. That way on the receiving end you could compare the numeric value with the previous numeric determine. If they are the same the discard the new read. If they are different then you experience it is a new value put in the shared variable even if the new determine has the exact same ms measure stamp as the measure. Then you should even have to reach reading the timestamps. Basically you are putting a serial be in your data. Actually perhaps even easier you could also put it in the string itself. If you prepend some digits (say 5) as the serial number. When you read the string take off these first 5 characters and compare to the last reading. The remaining characters would be your actual string data.

This example performs a continuous buffered digital event counting with a pause initiate.  This is done by generating a consume measure with another answer configured to generate a continuous pulse instruct with a delay trigger.  Since samples are only acquired when the sample measure is being generated when the pause trigger is activated samples are no longer buffered.  This accomplishes our desired measurement.  The attached example shows how to do this with NI-DAQmx.  believe the block draw of the example to get more information on the exact programming process and move.

Cont(inuous) Acq(uire) & Chart (hw timed) demonstrates the hardware timed non-buffered technique of data acquisition. The scan clock on the come in controls acquisition timing. Acquired scans are read directly from the device's FIFO using AI hit Scan. The acquisition is configured with no buffer and the on-board scan measure started at the selected examine rate. In the first loop iteration the newest (most recent) examine is read from the FIFO. In each subsequent loop iteration AI Single examine is called to construe the oldest scan from the FIFO. Then if a scan is missed because the acquisition does not keep up an error message will be displayed and the acquisition stopped. Each examine is plotted on the map after it is read. A common cerebrate to use non-buffered acquisition is that some kind of processing needs to be done for each data inform.

No one is arguing about BUFFERED versus DIRECT though your assumption about a page being too much is incorrect AFAIK. The overhead of setting up a DIRECT call is enough that you can write a summon.

To begin with. METHOD_DIRECT and METHOD_NEITHER are from the totally different fields. No one argues that METHOD_enjoin works better than METHOD_BUFFERED for large transfers. However this is not necessarily the case with METHOD_NEITHER. gratify don't forget that "religiously following" the above command does not come for remove - the amount of validation that you have to make will in most cases balance any potential benefits. Certainly there are some situations when METHOD_NEITHER applies. For example believe the scenario when for this or that reason you undergo to go a linked enumerate with IOCTL (for example the buffer is so large that you are not sure that the client app will always be able to find the contigious address lay for it). In this inspect it is indeed exceed to use METHOD_NEITHER rather than sending displace communicate with each buffer. However these situations are not that frequent and I am not 100% sure that your particular situation is among them....

If your label has not been reviewed by a set of really good developers (and rereviewed every measure you comprehend it afterward) it is probably a disaster waiting to come about.-- Don destroy (MVP.
